Go pros are the best for follow and stuff, but when your filming yourself on a jump, or like riding some fresh pow, its not the best, especially on the helment, it can be sick if its on the chest, but that is pretty much it.
but like again for follows, its super good, cause you dont have to care about pouinting the camerea at the right place, you look at the guy jumping, and its done. I got the none Hd one, and i wish i took the Hd one, there is a huge difference, night and day..
